New preprint with Camden MacDowell, M.D. Ph.D. on how information is passed from one brain region to another! We find interactions between brain regions are multiplexed, different dimensions of neural activity are shared with different cortex-wide networks of regions. biorxiv.org/content/10.110…

Exciting work by Charles M. Greenspon Giacomo Valle sliman bensmaia (@[email protected]) Cortical Bionics Research Group et al using intracortical microstimulation of S1 to restore tactile feedback in brain-controlled bionic hands! Key step towards closed-loop control of artificial effectors! 🦾🧠⚡️ 👉biorxiv.org/content/10.110…

Very excited to share our recent work w/ Calvin Kao & Guillaume Hennequin! We investigated when & why motor preparation arises in RNN models of motor control. Is preparation optimal for RNNs performing delayed reaching tasks? Spoiler: it is! (1/5) biorxiv.org/content/10.110…

Excited to share inspiring work from Sean Perkins in Mark Churchland lab highlighting how basic science insights can usefully constrain BCI decoders, allowing simple algorithms to outperform much larger neural networks!🧠🦾 "Simplicity is the ultimate sophistication" — da Vinci

Cool new task by @AliceCMo Leslie Sibener, PhD Tiffany Chen Daniel Wolpert Rui Costa et al where mice learn to move a joystick into covert spatial targets, with interesting interactions between initial exploration, RL & individual differences in control strategy! 👉biorxiv.org/content/10.110…

Controlling a hand prosthesis with a brain interface is an incredibly hard problem. How can we train a BCI to produce precise hand movements? We present LSTT: a protocol for training accurate BCI hand grip control A 🧵 and a preprint: biorxiv.org/content/10.110… led by Andres Agudelo-Toro

I’m excited to share the first paper of my PhD! arxiv.org/abs/2306.10168 1/

Brilliant paper from Yiting @EricFinks Duo Xu (Many) in @dan_h_oconnor lab! 🧠🐭 “flexible selection of an appropriate action in response to a sensory input can occur via configuration of preparatory states in the motor cortex” 👉biorxiv.org/content/10.110…

Thought provoking paper by Jackie Birnbaum & munib hasnain in Mike Economo lab trying to isolate dynamics related to cognition🤔vs movement💪in the mouse brain!🐭🧠 Uninstructed movements can be highly context-specific, making this a very thorny issue! biorxiv.org/content/10.110…

Ever wonder how the pianist can perform a new piece from sheet music, or effortlessly play a well-practiced sonata in a concert? We study the underlying neural circuits in ‘piano-playing’ rats and show that motor cortex and basal ganglia play different roles.

Ever wondered whether the dynamics learned by LFADS-like models could help us understand neural computation? Chethan Pandarinath,Andrew Sedler, Jonathan McCart, and I developed ODIN to robustly recover latent dynamical features through the power of injectivity! 📜 1/ arxiv.org/abs/2309.06402…

🧵When and how does the striatum impact learning? Postdoc Kim Reinhold trained mice to reach for food pellets. They didn't know when the food was available so they had to reach randomly. One day, we provided a cue telling them the food was there. biorxiv.org/content/10.110…

Can GABA excite sensory afferents in the spinal cord? Dave Bennett says yes. In collaboration with Elvira Pirondini, Dave and CJ Heckman labs, Lucy Liang and Amr Mahrous checked in monkeys in this beautiful preprint. Amazing work from a stellar duo check it out! #neuroscience

Check out our new preprint: An opponent striatal circuit for distributional reinforcement learning, biorxiv.org/content/10.110…, by Adam Lowet, with Qiao Zheng, Melissa Meng, Sara Matias, myself, and @naoshigeuchida. 1/6

I wrote a few thousand words about the cerebellum for Current Biology … check it out if you’d like to learn more about “the little brain” authors.elsevier.com/a/1iOZX3QW8S2T…

Finally, the results of many exciting and inspiring hours with Josep Maria Balaguer Stanisa Raspopovic Marco Capogrosso spent on analyzing the effects of peripheral nerve stimulation on neural processes in the spinal cord and brain, are out! cell.com/cell-reports/f…

1/7 For the past decade, our team at Meta Reality Labs (previously CTRL-labs) has been dedicated to developing a neuromotor interface. Our goal is to address the Human Computer Interaction challenge of providing effortless, intuitive, and efficient input to computers.
